摘要： A multisystem log stream of a multisystem environment is compressed. The oldest record needed for each system that can write or delete entries from the multisystem log stream is tracked, and that information is used in compression of the log stream. The block ids associated with those oldest records are maintained within a vector, and when the vector is updated, a determination is made as to whether the entry in the vector that it replaced previously contained the lowest block id in the vector. If so, all the records having block ids lower than the new lowest block id in the vector are deleted.

摘要： When a log stream has a determined amount of reusable space, the log stream is compressed in order to free up the reusable space. Compression of the log stream includes rewriting one or more active entries located at one or more positions of the log stream to one or more other locations, either within the same log stream or on another log stream. Thereafter, the rewritten entries are deleted from their previous positions within the log stream. Additionally, one or more logically deleted entries of the log stream is removed from the log stream. The resulting log stream is a compressed log stream.

摘要： Work units are identified, managed and reported on as a group or enclave. The dispatching priorities of the work units are separated from the address spaces executing the work units. Instead, the dispatching priorities are tied to the priority of the enclave allowing work units to be executed within an address space at a priority independent from the address space. Additionally, resources used by the work units are accumulated and allocated to the requestor of the work.

摘要： The frequency at which a multisystem log stream is compressed by a system of a multisystem environment is adjusted in real-time. The rate at which the multisystem log stream is compressed by the system is ascertained. That rate is relative to how frequently the multisystem log stream is compressed by other systems of the multisystem environment. The frequency with which the system compresses the multisystem log stream is then adjusted in real-time. Thus, the frequency at which one system of the multisystem environment compresses the log stream is relative to the frequency at which other systems of the multisystem environment are compressing the log stream.

摘要： PLO (perform locked operation) instructions containing blocking symbols are executed on each of multiple processors in a computer system to control coherence in data structures which may be changed by any of multiple processors in a computer system. The blocking symbol is extracted from a PLO instruction instance when invoked by its executing processor. Then the processor hashes the blocking symbol using hardware-microcode (H-M) to generate the location of a lock field in protected storage. The PLO instruction's blocking symbol is associated with a computer resource unit by software providing the PLO instruction, and the blocking symbol then associates the resource with a protected lock through the hashing operation on the blocking symbol. A processor must obtain the lock for a blocking symbol before the executing PLO instruction instance is allowed to make access and change the resource unit associated with the blocking symbol. The blocking symbol controls the PLO operations by serializing simultaneously PLO instruction access requests being made by multiple processors to the same resource unit using the same blocking symbol to allow only one PLO instruction instance to have exclusive access to the resource at a time.
摘要翻译：在计算机系统中的多个处理器中的每一个上执行包含阻塞符号的PLO（执行锁定操作）指令，以控制可由计算机系统中的多个处理器中的任何一个处理器改变的数据结构中的一致性。当由其执行的处理器调用时，从PLO指令实例中提取阻塞符号。然后，处理器使用硬件微码（H-M）对阻塞符号进行散列，以产生受保护存储中锁定字段的位置。 PLO指令的阻塞符号通过提供PLO指令的软件与计算机资源单元相关联，然后阻塞符号通过对阻塞符号的哈希操作将资源与受保护的锁相关联。在允许执行的PLO指令实例进行访问并更改与阻塞符号相关联的资源单元之前，处理器必须获得锁定符号的锁定。阻塞符号通过使用相同的阻塞符号将多个处理器进行的PLO指令访问请求同时序列化到相同的资源单元来控制PLO操作，以允许一次只有一个PLO指令实例对资源进行独占访问。

摘要： One system of a multisystem environment takes over log entries owned by another system of the environment. When a system owning entries on a primary log stream is inactive (or a sync point manager on the system is inactive), another system of the multisystem environment writes the log entries corresponding to the inactive system to other locations. The entries within the other locations are not owned by any system. Thus, the resource managers associated with those log entries are eligible for restarting on any system of the multisystem environment. However, all resource managers involved in a common set of transactions are to restart on the same system. The other resource managers can restart on another system. When one of the resource managers restarts on a system, the system takes back ownership of the entries associated with the common set of transactions.

摘要： Provides a processor CLE (CPU lock element) for each processor in a protected storage in a multi-processor computer system. Each CLE contains a blocking symbol field (called herein a PLT, program lock token, field), a lock field H, and a wait field W which is used to chain plural CLEs currently having the same blocking symbol. When the lock field H is set to a lock held state, it indicates the associated processor has exclusive rights to access a data resource unit associated with the blocking symbol in the CLE entry. When the wait field in a lock entry contains a pointer to another lock entry and the H field in the lock entry indicates a not held state, the associated processor is waiting for the resource and cannot further execute its PLO instance until it later gets set to the lock state, which is done by the processor of the prior CLE in the chain when it completes execution of its PLO instance. Each PLO instruction also has operand fields, and a function code (FC). The FC controls the manner of processing done by the PLO instance on its operands. Blocking symbols are specified by software to enable the software to utilize hardware enforced serialization of multi-processor accesses simultaneously requested for accessing the same data resource in the computer system. The plural processors may simultaneously, and at any time, initiate PLO instances for the same or different blocking symbols. When different processors simultaneously execute PLO instances having different blocking symbols, the processors may execute in parallel without conflict. But if the different processors simultaneously execute PLO instances having the same blocking symbol, the processors cannot execute in parallel without potential conflict, and the processors must serialize the execution of their PLO instances for accessing the same resource. In the latter case, their CLEs are chained through pointers in wait fields of the CLEs.
